# Mathematics Lesson Note For SS2 (SecondTerm)

# Below are the 2022 complete SS2 Second Term Mathematics Lesson Note

Week Two: Straight Line Graphs

**INTRODUCTION:**

**Linear Graphs**

A **graph** is a picture that represents numerical data. Most of the graphs that you have been taught are **straight-line** or **linear graphs**. This topic shows how to use linear graphs to represent various real-life situations.

If the rule for a relation between two variables is given, then the graph of the relation can be drawn by constructing a table of values. To learn more, click **here**.

Week Three: Inequalities

**INTRODUCTION:**

When working with linear equations involving one variable whose highest degree (or order) is one, you are looking for the one value of the variable that will make the equation true. But if you consider an inequality such as x + 2 < 7, then values of x can be 0, 1, 2, 3, any negative number, or any fraction in between. In other words, there are many solutions for this inequality. Fortunately, solving an inequality involves the same strategies as solving a one variable equation. So even though there are an infinite number of answers to an inequality, you do not have to work any harder to find the answer. To review how to solve one variable equations.

Week Four: Graph of linear inequalities in two variables

**INTRODUCTION:**

We use **inequalities** when there is a range of possible answers for a situation. “I have to be there in less than 5 minutes,” “This team needs to score at least a goal to have a chance of winning,” and “To get into the city and back home again, I need at least $6.50 for train fare” are all examples of situations where a limit is specified, but a range of possibilities exist beyond that limit. That’s what we are interested in when we study inequalities—possibilities. To learn more, click **here**.

Week Five: Application of linear inequalities in real life

**INTRODUCTION:**

Linear programming is the process of taking various linear inequalities relating to some situation, and finding the “best” value obtainable under those conditions. A typical example would be taking the limitations of materials and labor, and then determining the “best” production levels for maximal profits under those conditions. To learn more, click **here**.

Week Six: Algebraic Fractions

**INTRODUCTION:**

Algebraic fractions are simply fractions with algebraic expressions on the top and/or bottom. When adding or subtracting algebraic fractions, the first thing to do is to put them onto a common denominator (by cross multiplying).

Week Seven: Review of first half term’s work and periodic test

This week, we would be doing a revision of all that we learned, in the first half of the term.

Week Eight: Fraction Cont’d

Week Nine: Logic

**INTRODUCTION:**

A statement is a verbal assertion which can determine either true or false. Sometimes, two statements comes together which is known as the compound statement. In this page, we are going to discuss about compound math statement concept. To learn more, click **here**.

Week Ten: Chord Properties of Circles

Week Eleven: Circle Theorems: Angle properties of circle

Week Twelve: Revision

This week, we would be doing a revision of all that we learned during the term.

Week Thirteen: Examination

Afterwards, we would write an examination, which would test our knowledge of what has been taught so far.
